Effect

Manual activation

When used from the Bag in a wild Pokémon encounter, it will attempt to catch the wild Pokémon with a catch rate modifier of 2×.

If used on an Ultra Beast, the catch rate modifier is instead set to 0.1×.

The Ultra Ball cannot be used in situations in which Poké Balls cannot be used, such as in wild battles with two or more opponents currently present or against a trial Pokémon. If used in a Trainer battle (except if used as a Snag Ball on a Shadow Pokémon), the opposing Trainer will deflect it, wasting the ball. If used on the ghost Marowak, it will dodge it, wasting the ball.
